Blackleg on potato can be caused by either Pectobacterium or Dickeya species, and they often work together in different combinations to cause this disease. Blackleg can result in stem decay, severe seed decay and sometimes lack of plant emergence in severe cases. This Hort Innovation and RM Consulting Group (RMCG) factsheet provides information on managing blackleg in potato crops.

This research summary describes work assessing late blight of potatoes using spectral imagery collected by a drone.

This fact sheet provides guidance on the importance of monitoring soil-borne diseases, including tips for understanding and managing soil-borne disease risks.

Soil health is closely linked to soil microbiology. This fact sheet outlines information on a broad group of soil microbes including fungi, bacteria and pseudomonas, and explains how different levels, numbers and ratios of these microbes can impact the overall health of your soil and crops.

The Potato Pest and Disease R&D Coordination project and the Soil Wealth and ICP project, together with McCain and Nutrien, delivered an informative session on biologicals R&D resources, products and testing options for potato growers.

Keeping up to date with international pest and disease threats is important. This ongoing project conducted a scan of the most recent research and development on international potato pests, research previously conducted in Australia on these pests and some ‘ready to use’ resources.

This poster provides a snapshot of variable rate application, the options available, why and how to do it, key questions to keep in mind and more information on the practical tips and tools available.

The diseases caused by Spongospora subterranea (tuber powdery scab and root hyperplasia) can cause significant yield and quality loss. Not all soils are equally susceptible to this disease. This 2020 report determined factors that resulted in Spongospora suppressive soils in New Zealand.

This guide produced by RMCG in 2020 was based on current knowledge on management of powdery scab, highlighting key factors that affect the risks of this disease and opportunities for effective disease management.

With a growing interest in the area of soil health and the wide range of products available, this fact sheet explores organic soil amendments, biologicals and biostimulants to help growers understand what these products are and how they work.

Explore the impact of hydrophobic soils on potato production and options for growers to assist with their management to improve potato yields.

The Australian potato industry is committed to building its capacity to respond to potential biosecurity threats. In addition to dedicated farm biosecurity officers and advisers, a range of farm biosecurity planning resources are available for growers, advisers and industry members to access. These resources are regularly reviewed and updated to reflect industry needs.

‘Know your salts’ takes an in-depth look at salinity and the salts that affect both plant health and soil structure, and guide potato nutrition.

This first fact sheet outlines the causes of salinity followed by key assessments and tests that will better inform your management decisions.

Learn about using the IrriSAT technology which combines evapotranspiration (ETo) and satellite imaging, and how to link this with data from direct soil moisture sensors, to help you schedule irrigation.

This NSW case study has shown that IrriSAT satellite images, used to monitor irrigation, can also help potato growers identify soil and irrigation problems across the pivot. Fixing the problems identified in this case study would have increased yield and revenue by between $7,600 and $10,800 under this half pivot.

This case study explains how the irrigation tool, IrriSAT, combined with soil moisture monitoring, provided important information to the grower about crop water requirements and actual soil moisture levels. This enabled him to manage his crop irrigation to maximise yield and quality.

Management of rots, both in the field and post-harvest, is an ongoing challenge for potato producers. Agronomists Marc Hinderager and Dr Pieter Van Nieuwenhuyse discuss a trial that was set up to explore the effect of sanitisers and/or drying on the development of post-harvest bacterial soft rot in potatoes.

Plant analysis is used as a tool to fine tune the nutrition of crops. The nutrient status of plants or parts of plants can be determined directly via laboratory analysis or estimated via in-field testing, while the overall health and nutrient status of a crop can be assessed via non-destructive sensing technologies.
